Sounds like a bad thermostat, or blown head gaskets. replace the thermostat with one from the dealer. If you still have the problem one or both head gaskets are bad.

High motor temperature


check for cooling system of the engine.. make sure the water is in full level.. check also if theres any coolants leak.. is your cooling fan working.. you must make it sure..

I have a problem with the code P0118 of my 2002 Jetta GL can you help me?


Make sure coolant level is as it should be. If level is low look for evidence of leak(s). Top off fluid if necessary. The engine coolant temperature sensor is a very common issue with these vehicles and may be the cause of your issues if no leaks are found. Also a faulty thermostat cans cause the sensors to read voltage high but most likely a sensor issue. The sensor is a potentiometer (variable resistor). The computer sends 5v through one of the wires this voltage goes through a resistor which will vary the voltage based on temperature sensed by the engine coolant temperature sensor. The sensor has a negative temparature coefficient meaning the resistance will go down when temperature is high and up when temperature is low. The less resistance the more of the 5 v gets back to the computer. The PCM detects this high voltage and set the check engine light on warning you of an issue. Whe this sensor goes bad it is usually accompanied by temperature gauge fluctuation or erratic operation and the cooling fans run long or all the time even though the vehicle is cold. Hope this helps.

I had a water leak on my 1996 GMC K1500 and ran hot. Fixed problem truck running good, but the temperature gauge is pegged high even with a new sensor. How do I fix the gauge?


Pull off the negative battery cable and unplug the sensor. See if the gauge needle returns to normal. Try tapping on the cluster to unstick the needle. No luck? Replace the temperature gauge.

The blue temp icon comes on as usual on start up thn as engine warms it goes off as you would expect but on long journeys it comes back on thn goes on and off. What could be the problem.


Faulty thermostat is most common problem. Blue lamp on indicates coolant not reached operating temperature.

Blue Lamp hould stay out when coolant reaches operating temperature. VW have updated the Coolant Temperature Sensor. Thermostat is opening too long allowing coolant to cool below operating temperature tripping Blue Lamp..

New sensor should be GREEN in color and lives on the coolant hose running back across the rear of the engine.

When getting one replaced make sure you get the 'O' ring and new plastic clip to hold it in, along with the Sensor. They are orderable separately and your VW parts guy will not offer 'O' ring and clip unless you ask.

Check coolant is circulating into the bottle on the inner fender .
These engines also suffer from failure of the coolant pump when the plastic impeller breaks up or comes off the drive shaft. this causes overheating.

Heating System


The Engine Coolant Temperature (ECT) sensor is mounted in the intake manifold and sends engine temperature information to the ECM. The ECM supplies 5 volts to the coolant temperature sensor circuit. The sensor is a thermistor which changes internal resistance as temperature changes. When the sensor is cold (internal resistance high), the ECM monitors a high signal voltage which it interprets as a cold engine. As the sensor warms (internal resistance low), the ECM monitors a low signal voltage which it interprets as warm engine.

See Figures 3 and 4
  1. Remove the ECT sensor from the vehicle.
  2. Immerse the tip of the sensor in container of water.
  3. Connect a digital ohmmeter to the two terminals of the sensor.
  4. Using a calibrated thermometer, compare the resistance of the sensor to the temperature of the water. Refer to the engine coolant sensor temperature vs. resistance illustration.
  5. Repeat the test at two other temperature points, heating or cooling the water as necessary.
  6. If the sensor does not meet specification, it must be replaced.
